American Speech-Language-Hearing Association - November 20, 2008
- Chicago, Illinois
2Asperger Syndrome
- Autistic psychopathy
- (Asperger, 1991 1944)
- 4 boys, ages 6-11 yrs.
- Marked problems in social interaction despite
appropriate language and cognitive skills - Onset after 3 years of age, but earlier than
schizophrenia - Familial
3Asperger Syndrome
- Asperger syndrome
- (Wing, 1981 1986 1989)
- First recognized as a diagnostic entity by the
World Health Organization - (ICD-10 1993)
- Soon after, recognized by the American
Psychiatric Association - (DSM-IV 1994)
4Asperger Syndrome
- Asperger syndrome is a serious and chronic
neurodevelopmental disorder which is presently
defined by social deficits of the type seen in
autism, restricted interests as in autism, but,
in contrast to autism, relative preservation of
language and cognitive abilities--at least early
in life. - Volkmar and Klin (2000)
5Asperger Syndrome Language Impaired or Not?
- They all have one thing in common the language
feels unnatural.
(Asperger, 1944 1991, p. 69) - If one listens carefully, one can invariably
pick up these kinds of abnormalities in the
language of autistic individuals, and their
recognition is, therefore, of particular
diagnostic importance.
(Asperger, 1944 1991, p. 70) - Unusual language profile
- Problems with conversation
- Unusual melody or flow of speech
- Atypical developmental history, including early
or late language emergence - Tendency to speak like an adult, with advanced
vocabulary - Use complex sentences
6Criteria DSM-IV and ICD-10
- According to DSM-IV TR (APA, 2000) and ICD-10
(WHO, 1993), individuals with Asperger syndrome
present deficits in two areas - Social interaction
- Eye to eye gaze, facial expression, body
postures, gestures to regulate social interaction - Immature peer relationships
- Lack of spontaneous seeking to share enjoyment,
interests, or achievements with others - Lack of social or emotional reciprocity
- Behavior
- Preoccupation with stereotyped, restricted
interests - Inflexible adherence to nonfunctional
routines/rituals - Repetitive motor mannerism stereotypies
- Preoccupation with objects or parts of objects
7Criteria DSM-IV and ICD-10
- According to ICD-10 (WHO, 1989), individuals with
Asperger syndrome may present deficits in - Motor skills
- According to DSM-IV TR (APA, 2000) and ICD-10
(WHO, 1989), individuals with Asperger syndrome
present NO DEFICITS in - Language
- Words by 2 yrs. communicative phrases by 3 yrs.
- No clinically significant general delay in
language (APA, 2000, p. 84). - Cognition
- Self-help skills
- Adaptive behavior (other than social interaction)
- Curiosity about their environment
8Criteria Gillbergs
- According to Gillberg and Gillberg (1989),
individuals with Asperger syndrome present - Social deficits
- Extreme egocentricity
- Poor appreciation of social cues
- Inappropriate social and emotional responses
- Limited interests and preoccupation
- Repetitive involvement with objects of interest
- Some interests more rote than meaningful
- Repetitive routines or rituals
- Imposed on self and others
- Motor clumsiness
- Frequent, but not always noted
9Criteria Gillbergs
- According to Gillberg and Gillberg (1989),
individuals with Asperger syndrome present - Speech and language peculiarities
- Delayed early development possible
- Superficially perfect expressive language
- Formal, pedantic language
- Odd prosody peculiar voice
- Impaired comprehension, especially with implied
meanings tend to encode literal interpretation - Nonverbal communication deficits
- Limited gestures
- Odd body language
- Inappropriate facial expressions
- Problems with proximity
10Criteria Szatmari
- According to Szatmari and colleagues (1989),
children with Asperger syndrome present at least
two of the following - Inflection abnormalities
- Talk too much
- Talk too little
- Lack of cohesive conversation
- Idiosyncratic use of words
- Repetitive speech
11Language An Essential
Criterion
- Unusual language abilities are an essential
characteristic of Aspergers syndrome and should
be included in future revisions of the DSM
criteria (Attwood, 2007, p. 203). - Receptive language deficits, including problems
with comprehension of sentences and following
complex directions (Koning Magill-Evans, 2001
Saalasti, et al., 2008)
12Neurology of AS
- AS Right hemisphere disorder
- (Ellis, Ellis, Fraser, Deb, 1984 Ellis
Gunter, 1999 McKelvey, Lambert, Mottron,
Shevell, 1995 Voeller, 1986) - Expresses as deficits with lateralized functions
of - Visuospatial organization
- Social-emotional processing
- Nonverbal communication
- Prosody
- Gestures
- Proximity
- Anatomical differences of right hemisphere found
in SPECT imagining -
13Neurology of AS
- Differs from autism, a left hemisphere disorder
(Escalante-Mead,
Minshew, Sweeney, 2003 Fein, Humes, Kaplan,
Lucci, Waterhouse, 1984) - Expresses as deficits with lateralized functions
of - Language processing and production
- Beyond the cerebral cortex
- AS Subcortical disorder
- (Schultz, Romanski, Tsatsanis, 2000)
- Amygdala
- Thalamus--impaired cortical communication
- AS Cerebellar disorder
- (McKelvey, Lambert, Mottron, Shevell,
1995) -
14Research Early Indicators
of Asperger Syndrome
15Research Rationale
- AS is often diagnosed in late childhood or
adolescence, whereas autism is now diagnosed much
sooner (Eisenmajer, et al., 1996 Howlin
Asgharian, 1999). - Earlier detection leads to earlier intervention.
- Diagnosis is the first step in preventing
potential behavioral and emotional issues common
in AS (Attwood, 2007 Volkmar Klin, 2000). - There remains controversy whether AS and autism
are different disorders (Bishop, 2000 Schultz,
Romanski, Tsatsanis, 2000 Volkmar Klin, 2000). - While we know what the earliest symptoms of
autism are, we do not know the earliest signs of
AS.
16Research Questions
- What are the earliest indicators of Asperger
syndrome? - What patterns of development are noted in the
social-pragmatic, communication, and behavioral
domains?
17Research Design and Procedures
- Retrospective case study design
- Solicit, gather, and copy archival family video
data - Child with AS ages 0-5 years
- Gather case documents from families of
individuals with AS - Qualitative inquiry
- Identify and code behaviors through video editing
and document review - Triangulate findings
- Construct video records illustrating findings
- Describe findings from data record
- Quantitative inquiry
- Visual inspection of tabulated data
- Descriptive statistical analysis of data
18Subject Selection
- 10 participants
- 7 complete video records (0-5 years of age)
- 3 incomplete video records (spanning at least 2
years from 0-5 years of age) - Complete medical and educational records
- 18 additional participants
- Complete medical and educational records
- No video
- Diagnosis of AS from at least two professionals
with expertise in ASDs - Normal hearing and visual acuity
- No concomitant medical issues affecting early
development
19Limitations of Video Analysis
- Limited data record
- Varying amounts of tape including subject
- Various amount of tape at each age interval
- No control over context
- Different social contexts different
communicative opportunities - Intimately personal at times
- Profanity nudity possible
- Quality of video varies
- Background noise
- Other people or their voices sometimes obscure
subject - Digital signal interference
20Results Social-Pragmatics
- Social Engagement
- 100 (8/8) of infants demonstrated social
engagement - Gaze behavior social smile responsivity to
people - Ages 1-5 months
21Results Social-Pragmatics
- Social Reciprocity
- 100 (8/8) of infants/toddlers showed turntaking
- Reciprocal play or vocalization
- Ages 5-18 months
22Results Social-Pragmatics
- Joint Attention
- 100 (8/8) of subjects demonstrated coordinated
joint attention - Ages 7-12 months
23Results Social-Pragmatics
- Initiation
- All infants/toddlers (8/8) started social
interactions - More prevalent in some than others
- Ages 6-18 months
24Regression of Social-Pragmatic Skills
- TARYN
- 0-18 mos.-typical
- 19 mos.-repetitive play with kitchen toy
- 23 mos.-repetitive action in puddle
- 29 mos.-lack of JA with grandma at Christmas
- 36 mos.-lack of JA with peer in bathtub
- 49 mos.-lack of social engagement with baby
sister - 58 mos.-lack of interaction with sister in pool
- 60 mos.-beginning to demonstrate JA at 5th
birthday
25Regression of Social-Pragmatic Skills
- ADAM
- 3-7 mos.-Typical
- 20 mos.-No response to mother
- 24-36 mos.-Joint attention diminished
- 41 mos.-Plays apart from peers
- 48 mos.-Low social engagement with family/peers
- 50 mos.-Lack of interaction with baby brother
- 57-60 mos.--Joint attention and interaction begin
to re-emerge
26Social-Pragmatic Development Social Engagement,
Joint Attention, Reciprocity, Initiation
27Social-Pragmatics Age 4-5 years
- Demonstrate a range of communicative functions
- Understanding needs of listener remains difficult
- Responding moves still not consistent
- Sharing enjoyment with others is not automatic
requires direction - Eye referencing is slow, awkward
- Joint attention is intermittent difficult to
evaluate due to eye referencing differences - Self-talk is still evident
- Theory of mind beginning to emerge, but an
obvious challenge
28Summary of FindingsSocial-Pragmatic Skills
- Emergence of foundational social-pragmatic skills
of social engagement, joint attention,
reciprocity, and initiation occurred for all
subjects. - For 7/8 (87), skills emerged in typical fashion.
- For 1/8 (13), skills were slightly delayed.
- All subjects experienced a loss of early
social-pragmatic skills - Characterized by slowing of eye referencing, loss
of interest in social activities, loss of joint
attention and initiation. - One subject who experienced developmental delays
had somewhat later regression of social-pragmatic
skills. - Skills gradually began to re-emerge.
- Significant deficits remained at age 4-5 years.

33Receptive Communication Development
34Receptive Communication Development
Of 28 subjects, only two parents described
regressive patterns. Others perceived
developmental delay in receptive communication,
most noting that their concerns began between 2-3
years of age when their child just seemed not to
be interested in or undestand language.
35Results Unusual Communication Acts
- NATHAN ROSS
- Low regard for listeners
- Odd vocal quality
- Unusual prosody
- Repetitive language
36Results Unusual Communication Acts
- ADAM MATTHEW
- Repetitive language Immediate echolalia
- Minimal
- Indicative of language processing difficulties
- Serves clear communicative purpose
- No evidence of delayed echolalia
37Summary of Findings Communication
- Expressive communication emerges at expected ages
or with slight delays. - Video Analysis
- 8/10 (80) subjects--typical development
- 2/10 (20) subjects--mild to moderate delays
- Chart Review
- Mean age of attainment for all expressive
milestones examined was in the average range.
38Summary of FindingsCommunication
- Receptive communication emerges at expected ages,
then slows or regresses. - Video Analysis
- 9/10 subjects (90)--typical dev up to age 20-24
mos. - Language processing issues develop
- Parallels regression in social-pragmatic domain
- 1/10 subjects (10)--slow processing from early
mos. - Chart Review
- Mean age of early skills is in the average range.
- Mean age of following conversation is delayed.
39Summary of Findings Communication
- Unusual communication acts
- Video analysis
- 10/10 subjects (100) showed odd vocal
quality/prosody - Some repetitive language was noted
40Results Behavior
- Obsessive-Compulsive Tendencies
- 10/10 subjects (100) exhibited some OC
tendency - Obsessive use of objects, characters
- 4/10 (40) subjects demonstrated hyperlexia
41Results Behavior
- Repetitive Behaviors
- Seen in 10/10 (100) of subjects
- Early indicators of need for order
- Precursor of cognitive inflexibility
- May involve purposeful or nonpurposeful play
- Occasional stereotypies (5/10 subjects 50)
42Results Other Indicators
- Play Behavior
- 10/10 participants (100) showed early
imaginative play by 4-5 years of age - Play schema somewhat rigid underdeveloped
- Constructive play was not common due to fine
motor deficits
43Summary of Findings Behavior
- Obsessive-compulsive tendencies are pervasive in
this population, and are evidenced early in
development. - 10/10 subjects (100)
- Repetitive behaviors are also common, and show up
as one of the first indicators of the disorder. - 10/10 subjects (100)
- Play must be scaffolded by adults
- May appear repetitive, or nonpurposeful
- Often needs help with construction toys
- Imagination begins to show by age 5
- 10/10 subjects (100)
- Cognitive inflexibility apparent in play schemas
44Conclusions
- Social-pragmatic domain
- Typical from ages 0-18/30 months
- Social engagement
- Joint attention
- Reciprocity
- Initiation
- These early social skills diminish.
- Communication domain
- Expressive language emerges essentially on time
for most children with AS. - Occassionally, a child with AS presents mild
delays. - Receptive language emerges appropriately until
18-30 months of age. - Language processing speed and accuracy diminish
at this time.
45Conclusions
- Communication Domain
- Unusual communicative behaviors emerge
- Repetitive language immediate echolalia
- Odd vocal intonation/prosody
- Behavioral Domain
- Typical development until 18-30 months
- Repetitive behaviors emerge
- Possible stereotypies
- Increased noncompliance perhaps due to lack of
processing
46Conclusions
- Children with AS present typical development
through the 0-18/24 month period. - A developmental regression occurs between 18-30
months of age. - Regression is characterized by
- Loss of joint attention
- Interrupted eye referencing
- Language processing deficits
- Emergence of repetitive behaviors
- Unusual play behavior
- This regression is not frequently reported by
parents. - Many parents first become concerned between 2-3
years of age, but do not describe a loss of
skills. - Loss of skills not as great as that of the
autistic regression.
